TO ALL WHOM Irr MAY eonennn:

Be it known that I, WILLIAM E. JERVEY, of the city of New Orleans, parish of Orleans, and State of Louisi anti, have invented a new and useful improvement in Burners for Petroleum, to be used in petroleum gas stoves, or for other e -poses; and Ido hereby declare the following to be a full, clear, and exact description of the some, reference being had to the accompanying drawings, forming a port of this specification, in which Figure 1 is sperspeetive view of my improvement.

Figure 2, a sectional view thereof.

Figure 3, a top view of the upper retort or furnace.

Figure 4, a bottom view of the some.

Figure 5, a view of heater cap.

Figure 6, a sectional view thereof.

Figure 7, a bottom view of the same.

My invention has for its object the supcrsedence of the use of white.or-red lead or other like substances; also the doing away with all screws and joints in the fabrication of petroleum gas burners; the sure, certain, easy, and thorough transmission of heat to the burner or interior retort orfiuid-ehamber the perfect combustion of all the gas that is created; the direct transmission, in an upward direction, of the flame to the article to be heated; and the more effectual prevention of leakage in'the lower retort by having it cast in one solid piece, thereby abandoning the use ofjoints, screws, serew-v alvem'the use of white or red lead, and the better and more regular retention of heat by dispensing with the use of conical rings and cross-wires, which always destroy this heat; the diminishing of the noise made by the escaping gas; and the attainment of many other advantages that need not be here-specified.

To accomplish these beneficial results, I construct a retort or fluid-chamber, A, figs. l and '2, cast in one solid piece of brass or other metal, discarding the use of all screws, screw-valves, joints of every description also doing away with the use of white or red lead, or other equivalent substances, so that it becomes a physical impossibility for any escnpeof gas but through the jet 9, which is a small hole drilled in the top of the retort A. Projecting upward from the bottom of the fluid-chamber A are arms D, (see figs land 2,) which act as supports to the upper or superior retort or furnace Rand at the some time as conductors of heat that is therein generated to the lower retort A, to the end of keeping up a regular and constant ventilation of the fiuid con" tained therein. These arms may be increased or decreased in number, in accordance with the amount of heat desired. F is a wire gauze to protect the gas from wind. As I have already made application for Letters Patent for fig. 3, (E, upper'retort or furnnce,) I do not consider it necessary to further describe it here.

Figures 5, 6, and 7, B, are views of a heater cep,'the intention of which is to spread the flume, and destroy the hissing noise madeby the'escuping gas.

By reference to the drawings the operation of my invention will be readily understood. The fluid is sup plied from a reservoir placed above the burner and stove in the usual way, and passes from the reservoir through a small tube connected with the tube G into the lower retort or fluid-chamber A. The flow of the fluid is reguluted by a stop-cock, but as I lay no claim to the reservoir, the tube leading therefrom, nor the stop-cock, I have not thought it'neccssary to delineate the same upon the drawings. So soon as the fluid is heated by the familiar methods sufficiently to volatilize a portion of it, such part, non transformed into an inflammable gas, escapes through the jet g and rises into the furnace E, which quickly becomes so entirely heated that a. complete combustion of the gas inevitably follows. 13 is a heater cap, which is also intended to rest on the arms D, the intention of which is to spread the flame, and at the sometime destroy the noise made by tho escaping gas. The intense heat imparted by the furnace and heateroop is communicated to the conductors D, which, from being enveloped in flame, become red hot,and by them a sufiicient degree of'hent is transmitted to the fluid-chamber to keep up a continual and active volatilization of the fluid, even when the some is of the heaviest quality. The gas or flame issues from the furnace E through the orifices I I, and is brought into direct contact with the thing to be heated, whatever that thing may be. It will be observed that there is no joint, screw, or screw-valve in my burner which requires a packing of white lead, (which will burn out,) and hence there in no leakage of gas or oil, as is the case in Grays, Strattens, Morrills arrangements, and all other with which I with which I have had any acquaintance, and consequently none of these evils con arise in mine, where all the causes for said'evils are obviated.

Having thus described my invention and explained its mode of operation, what I claim, and desire to secure Letters Patent for, is'

1. The lower retort or fluid-chamber A, when constructed substantially as described for the purpose set forth. 2. The combinatlon of heater caps B, wire protecting gauze F, and lower retort A, constructed and arranged in the manner substantially as shown imd described, and. for the purpose set forth.
